Modeling 3D euclidean geometry [PDF]
IEEE Computer Graphics and Applications, 2003 This article compares five models of 3D Euclidean geometry-not theoretically, but by demonstrating how to implement a simple recursive ray tracer in each of them. It's meant as a tangible case study of the profitability of choosing an appropriate model, discussing the trade-offs between elegance and performance for this particular application.

3D channel model in 3GPP [PDF]
IEEE Communications Magazine, 2015 Multi-antenna techniques capable of exploiting the elevation dimension are anticipated to be an important air-interface enhancement targeted to handle the expected growth in mobile traffic. In order to enable the development and evaluation of such multi-antenna techniques, the 3rd generation partnership project (3GPP) has recently developed a 3 ...

Statistical modeling of facial aging based on 3D scans [PDF]
, 2010 This thesis presents an approach to the modeling of facial aging using and extending the Morphable Model technique. For modeling the face variation across individuals, facial expressions, and physical attributes, we collected 3D face scans of 298 persons.

Rubber Impact on 3D Textile Composites [PDF]
, 2011 A low velocity impact study of aircraft tire rubber on 3D textile-reinforced composite plates was performed experimentally and numerically. In contrast to regular unidirectional composite laminates, no delaminations occur in such a 3D textile composite ...

Re: Using Space-Based Investigations to Inform Cancer Research on Earth
Journal of Urological Surgery, 2015 In the Universe, four main forces are effective. These are weak nuclear force, strong nuclear force, electromagnetic force and gravitational force. Gravity is the attractive force between all matter.

ACM Transactions on Graphics, 2010 We present a new sketch-based modeling approach in which models are interactively designed by drawing their 2D silhouettes from different views. The core idea of our paper is to limit the input to 2D silhouettes, removing the need to explicitly create or position 3D elements. Arbitrarily complex models can be constructed by assembling them out of parts

Studying stress-strain state of gear billet using mathematical models depending on clamping forces in 3 and 6 cam self-centering chucks [PDF]
Омский научный вестник, 2020 The article discusses the results of studies of the 3D model of the gear wheel by the finite element method (FEM) in the stressstrain state (VAT). The model is in a state of static equilibrium in the presence of various basing mechanisms.
